Abstract: A method comprises storing first transaction data for a first transaction producing a first version of a first dataset, second transaction data for a second transaction transforming a first version of the first dataset to a second version of the first dataset, and third transaction data for a third transaction transforming the second version of the first dataset to a third version of the first dataset; storing dependency information indicating a first dependency of the third transaction on the second transaction and a second dependency of the second transaction on the first transaction; receiving a first instruction to revoke a first permission of a first user to access the second version of the first dataset; automatically revoking a certain permission of the first user to access the third version of the first dataset based on the dependency information.

Abstract: The present disclosure relates to a system for making or assembling fiber optic connectors that allows a pre-terminated fiber optic cable to be made compatible with any number of different styles or types after optic connectors or fiber optic adapters. The present disclosure also relates to a fiber optic connector having first and second pieces connected to twist-to-engage interface and also including a rotational interlock. The present disclaimer relates to a fiber optic connector having a boot that mounts in multiple different axial positions.

Abstract: An ink, and products formed from the ink, formulated at least in part from ceramic particles. The ink is formulated so that it can be used in additive manufacturing processes to form three-dimensional printed bodies. The three-dimensional printed bodies can have graded density and can be infiltrated by an infiltration material.

Abstract: An underwater communication method includes creating an air column in a water body using a device including a device body, an air column-generating component, and a transceiver, thereby forming an air column to a surface of the water body. A signal is transmitted, received, or a combination of transmitted and received using the transceiver through the air column to the surface of the water body.

Abstract: A semi-passive cooling system for a component exposed to a fluid flow utilizes a hierarchical vasculature and a sacrificial transpirant to cool the component. The component includes a body that defines a transpirant reservoir and the hierarchical vasculature. The transpirant is configured to transition between a solid phase and a vapor phase over an operating temperature range of the component.

Abstract: A composition includes a plurality of microparticles, where the microparticles comprise agglomerates of nanopowder, wherein the nanopowder includes a material selected from the following: a ceramic material, a metal, an alloy, a polymer, or a combination thereof. The microparticles are characterized by having an essentially spherical shape, nanograin features substantially identical to nanograin features of the nanopowder prior to formation into the microparticles, and a nanoscale porosity defined by the nanograin features. The plurality of microparticles have an essentially uniform size relative to one another. Moreover, the composition has flowability having a Hausner Ratio representing tapped density:bulk density less than 1.25.

Abstract: A method for spatial and intensity control of remote foci locations of an optical beam generated from a light source. First and second, axially-aligned, non-diffractive foci are created by passing the optical beam through a phase mask and a Fourier lens. The phase mask q(s) is designed to have an axial response according to the following equation: E ? ( u ) = ? - ? + ? ? q ? ( s ) ? exp ? ( - 2 ? ? ? ? u 0 ? s ) ? exp ? ( 2 ? ? ? ? us ) ? ds . The properties of the phase mask may be altered to independently vary location and intensity of the first and second foci.
